Moveable guide lines in Lens Correction

It would be very nice and useful to have adjustable guide lines in the  Lens Correction filter.  The grid never seems to line up with critical elements that need to be straighten.  Moveable guide lines that can be placed right on or next to elements would be a great help.  It would also be nice if the dialog box read the exif info to remind you what lens you were using.  And a way to record setting for particular lenses that you could add notes to would also be very helpful.  thanks jeff

Elements using the Camera Raw plug-in doesn’t allow for lens-corrections.  Since you’ve posted your question in the Elements forum, is that what you’re using?  The much more expensive regular Photoshop hosting the camera-raw plug-in and the less-expensive Lightroom do allow selecting lens profile corrections.
The Camera Calibration area you refer to only deals with raw camera profiles for color rendition, not lens profiles that would correct geometric distortion.
A more fundamental question is whether there are actually lens-distortion-correction profiles for a FinePix HS10.  Usually Adobe supplies lens profiles for most Canon and Nikon DSLRs although there are a few others for other brands and types of camera, with a Fuji point-and-shoot having less chance of having a lens-profile created by Adobe.
There is an Adobe Lens Profile Downloader tool for getting third-party lens-profiles and checking it just now, it appears there is a raw profile for the FinePix HS10/HS11 built-in lens, but you still need to be using an Adobe product other than Elements to apply such a profile.

  • Feature Suggestion: ruler guides instead of grid in Lens Correction

    In my work, I photograph two dimensional artwork in artist's studios or galleries which do not have the space, time,  or facilities to allow for perfect positioning when taking a picture. Since these photos are intended for print, it is essential that they are well aligned w/o being distorted. While just eye-balling works well for ordinary photos, these are doubly complicated because the image itself is contained within a four-sided shape that has to be "square."
    I often need to use the custom tab of Lens Correction to adjust vertical or horizontal perspectives. In these cases, the problem isn't the distortion inherent in a particular lens, it is a problem due to the angle of the camera or to where I had to stand to take the photo, usually w/o tripod and often not hanging on the wall.
    If I had the same kind of dragable guides I have in photoshop and could set them before starting, I wouldn't have to eye-ball it so much. I have to keep going back to PS to see if I nailed it and (usually) start over.  The grid is not much help, regardless of size, because I have to choose whether to position it for the horizontal line I'm trying to achieve or for the vertical, but not both. (Not to mention that dragging and positioning the grid isn't exactly a piece of cake!). If I could place four guides where I need them, I would be better able to tell how each nudge of the slider is affecting the image.
    It's hard to describe the problem but, if you create a square custom shape then use the 3-d controls to turn it sideways a few degrees and tilt it slightly back, you see what I'm up against.

    There would also be able to simply add the "perspective"as in Photoshop, probablyeasier to develop and integrate the interface.

  • Lens correction help needed: Nikon 14-24 used in model shoot...

    Hello,
    I just finished a model shoot with 9 models standing in a horizontal line relative to the camera.  Because of the very short working distance I had to use a Nikon 14-24mm lens to fit everyone in, resulting in the end girls being noticeably distorted (unpleasantly "wide").  They certainly won't like that!
    I've opened the raw file in CR, but have not found settings for lens correction that fix this.  CR has the correct lens profile, but no matter how I play with the settings manually or automatically, things just don't look right.  Similarly, if I open corresponding TIFF in Filter -> Lens correction, I still run into the same issue.
    I've enclosed a sample out-of-the-camera image so you can what I'm talking about.  Hoping there's a way to correct the twp outermost girls w/o sacrificing those in the middle...  They are much slimmer than in the shot.
    Running PS CS 5.5 on Win7/64
    Thanks!

    Hi Toasted
    I've seen the adds for the DxO Viewpoint and thought they had a great idea on their hands providing it as a Plug-in. However, I've been using the full DxO Optics Pro as my Raw file editor for a couple of years now, and ran your shot through that, and not the plug-in. 
    Judging my my results, I think the full version is a more powerful tool; the "Volume Anamorphosis" correction in the full version is a semi-automated tool. Simply applying the correction at the initial automated setting still left me with some distortion in the models at either end, which was especially noticeable in the girl on the extreme right. However, I then manually tweaked the setting to the maximum available, to get the result above.
    Now, there's no such thing as a free lunch, and you can't get something for nothing, and the same applies here. What's actually happening is that the Volume Anamorphosis is being "corrected" by re-introducing a set amount of Barrel Distortion into the image, oh, and the image has also been cropped, which is most noticeable in the bodywork of the cars on the left and right, but this is unavoidable. It isn't too obvious here, but if you were to have strong horizontals or verticals in the image, you'd see the curvature in them very easily.
    Take a look at my own example below.
    This was taken with a Tokina 11-16mm f2.8, and in the original the guitarist on the left, and the keyboardist on the right, both had the dreaded "squished head" effect! As you can see that's been fixed, but if you look at the pipes above the lights at the back, the line of the monitor cabinet at the lead singers feet, and the microphone stands, you can plainly see the curves... which is still infinitely preferable to distorted heads!
    Good luck

  • Accuracy of Lens Correction in LR3 or 4

    Hi! I recently bought my Fuji X10 und downloaded LR4 (beta). Im quite new to LR & RAW, but learning fast.
    Since there is no LCP for the X10 available yet, I'm doing lens correction manually. But the manual correction is quite limited, especially for the 28mm wide angle distortion of the X10.
    My efforts result in almost perfect horizontal & vertical lines in the center, but especially the horizontal lines spread towards the edge.
    http://dl.dropbox.com/u/4978642/Bildschirmfoto%202012-01-21%20um%2014.37.01.png
    Now I would like to know, if a later available LCP would correct this further and straighten all lines? Hoping not to need Photoshop to do the job.
    THX for any comments.
    Oliver
    If you don't have a Dropbox Account, get one free here: http://db.tt/y1XYyIg

    Manual lens correction model is limited and only account for lower order distortion terms. The distortion used in the LCP is more powerful and can account for higher order distortion terms. You can build your own custom lens profiles using the Adobe Lens Profile Creator http://labs.adobe.com/downloads/lensprofile_creator.html. Or see if others have built and shared the same lens profile using the Adobe Lens Profile Downloader.

  • ACR 6.1 vs DXO Lens Correction?

    I have been experimenting with the lens correction module in ACR 6.1, which has profiles for two lenses I own, the Nikkor AF-S 18-70mm f/3.5-4.5 G and the Nikkor AF-S 70-200mm f/2.8 G IF-ED VR, and am quite pleased with the results. The 18-70 lens is a decent consumer grade zoom that has good resolution and little chromatic aberration, but which suffers from distortion at the wide end and vignetting at large apertures. From visual onscreen editing, the vignetting is completely removed from the images and the barrel distortion at wide angle settings is sufficiently well controlled that thus far I have seen no need for manual touching up of the distortion correction.
    DxO (an Adobe rival) has criticized the ACR module as offering undercorrection of distortion and vignetting under some conditions, suggesting that the Adobe profiling procedures are not sufficiently rigorous. That may be so, but thus far I have seen no major defects and they gave no examples and I am wondering what the experience of other ACR users might be.
    http://www.dpreview.com/news/1005/10052001adobedxoensprofile.asp
    The 70-200 zoom was highly regarded for use with APS sized sensors, but full frame users have noted an alarming degree of softenss in the corners of the image. With ACR, one could attempt to provide extra sharpening at the edges of the image with an adjustment brush, but DXO claims to automatically correct for uneven sharpness across the image field. They don't say how this is achieved, but the web site explanation hints at something more sophisticated than a variable unsharp mask (perhaps a variable deconvoluiton algorithm) and I would be interested how this works out in practice.

    I hardly know where to start!
    Anyway, looking at the list of available lenses, the list for Photoshop Nikon optics is extensive, and also has at least one error. The list for ACR is far less, and my principal lens isn't present. The problem with that item is that, if you choose Custom and your lens isn't on the list, it reverts to the first lens on the list and corrects the image for that. In Auto, it tells you it isn't on the list, so I would urge the use of Auto at all times when operating with commercially available lenses.
    In PSCS5, my basic lens also is not present; (18 to 105 mm), but there is a lens, 18 to 125 which is not in the Nikon line. This appears to be an error. Is this the 18 to 105?
    I  have serious reservations with the idea of "Photographer Empowerment" with respect to lens corrections. I hope that if you publish this data it is in it's own category to which I can ignore. Lens measurement, data collection and conclusions is an intense activity and is best left to the professionals as is photo editing software. DXO knows what they are doing. The concept of "Photographer Empowerment" indicates to me Adobe does not know what it is doing. This makes me very nervous, to say the least.
    Let me give you an example. I ran an image from my 70 to 300mm lens, which is on the charts, through both DXO and ACR 6.1, then set one over the other in Layers. Switching back and forth showe a vast difference in the correction for barrel/pincushion and vignetting. Which is right?
    FYI, I always have two sets of raw data when anticipating running the DXO corrections so that there is no preconditioning by either party when running such tests. Also, I use DXO only for lens correction activities. Their RAW converter, imo, cannot compare to even CS3, for reasons I won't go into here. There are cheaper programs for doing barrel, vignette and such, but DXO also provides corrections for other lens errors, which makes it well worth while.
    To answer my own question is that, in architectural photos, DXO is on the money. The only way to tell for sure is an optical setup that is precise and repeatable.
    Finally, here is a site that uses the DXO software to provide lens tests that are extensive and comprehensive, all for the practicing photographer. Using their data for inclusion in the ACR correction would be a good start, not Photographer Empowerment.

    I use them once I have narrowed down the field to a few lenses and haven't been disappointed.

  • Adding Guide Lines In Photoshop

    Hi All,

  • Lens corrections in PSE raw

    I cannot determine whether lens corrections work in ACR 6.4 using Elements 9. I know the lens correction tab is not available - but does that mean no lens corrections are applied at all - or does it simply mean I cannot manipulate the correction beyond the default provided in ACR?

    ACR will use whatever the ACR default is for the specific camera the raw file is from.  I say this because with ACR 7, at least, you can enable Auto-CA (a manual lens correction) as the default for a particular camera when using ACR with PSE10, by editing the ACR camera-defaults file with a text editor.
    Here is what I did on Windows 7 to enable Auto-CA for my brother who does not use LR nor PS, only PSE:
    1) Open a new RAW image for the camera you are wanting to affect the settings of in PSE/ACR that has never had any edits done.
    2) Go to the Camera Calibration tab in ACR (a black camera icon) and change the Process Version to 2012—this will update the camera-defaults file to have PV2012 values which include the Auto-CA.  You can skip this step if you are using an older version of PSE.
    3) Click the 3-dots-three-lines icon at the right of where it says Camera Calibration, and choose Save New Camera Raw Defaults from the bottom of the menu that pops up.  This step will create a or update the camera-specific ACR-defaults file for your computer user.
    4) Exit ACR with Cancel, and Exit PSE.
    5) Using Windows Explorer, browse to the following folder under your user folder:  c:\Users\yourusername\AppData\Roaming\Adobe\CameraRaw\Defaults\ 
    The AppData folder is hidden so you may need to type this part into Explorer’s address bar.
    6) In the Defaults sub-folder there should be one or more files named:  Default_somehexdigits.XMP.
    7) Open each of these XMP files and find the one that matches the camera the raw file was from.  The value of the crs:KeyString attribute is the camera name.
    8) Further down in this XMP file, look for several lens-correction-specific attributes and change them to be the following:
           crs:LensProfileEnable=”1”
           crs:AutoLateralCA=”1”
           crs:LensProfileSetup=”LensDefaults”
    The other parameters for Vignetting and Perspective are for manual adjustments and you don’t want to set these other than “0” for your defaults although you can set them for an individual image by editing its XMP file.
    9) Save the XMP file.
    10) Start up PSE and open a new RAW file and see that the lens-distortion and Lateral-CA has been corrected as much as the auto-correction can do.

  • Nikon 10-24 Lens Correction

    I just discovered Lightroom's lens correction presets for specific lenses. While many of my Nikon lenses are listed, my latest lens (the Nikon 10-24mm f/3.5-4.5G ED) is not listed. It's one of Nikon's newest lenses.
    I'd like to be able to quickly correct distortion in my photos. Does Lightroom add additional lenses over time to their list of presets?
    If not, are there 3rd party presets for correction that I could take advantage of?
    Thanks!

  • Sony FE 28-70mm in camera + Lightroom lens correction = double correction or overcorrection?

    Hello,
    I have a Sony A7 with Sony FE 28-70mm kit lens. On the Sony A7, if i select "Shading Compensation" in the camera menu, the camera corrects vignetting in the saved raw file. I have experimented by taking two raw photos, with in camera Shading Compensation turned on and off. I then imported the photos into Lightroom. I then tried turning lens compensation (vignetting) on and off in Lightroom. This confuses me. In the first image (In camera ON and Lightroom correction ON) it looks like vignetting is completely gone. With in camera ON and Lightroom lens correction OFF, there is still clearly remaining vignetting. With in camera OFF and Lightroom ON there is also clearly remaining vignetting
    Can someone tell me what the recommended course of action is? Is the Sony in-camera lens correction worse or better than Lightroom? Neither the in-camera nor Lightroom's correction will correct vignetting completely on their own. Does that mean that the Lightroom correction is supposed to be used in tandem with the in camera correction to achieve full vignetting correction? There is lacking information/documentation of this feature, I have looked at both Sony A7 help guide and Adobes documentation about lens correction without finding any info about this situation.
    Thank you.

    "Shading Compensation" is probably saved as metadata tag in the raw file but the raw file data is not corrected.  This metadata is probably used in the included Sony software to automatically correct the raw for "Shading Compensation" but Lightroom probably does NOT use this data.  You will hopefully get a reply from a Sony user.

  • Nikor 28 to 105 not listed in lens correction Light Room 5 cc

    I watched a tutorial in Utube. Author said he had never tried to use a lens correction and found the lens not in the list.
    My first try, and I can not find Nikon Nikor 28 to 105 MM 1:3:5 4.5 D.

    That is not a practically empty xinitrc - that file only needs one line: exec WM.  Other things are entirely optional, and some of them very useful, but I'd encourage you to stick with the simplest xinitrc that will do what you require.
    Is slim involved?  Probably.  That is the source of many problems.  But to start narrowing this down, I have 3 suggestions:
    1) temporarily (at least) change your inittab to default to runlevel 3 ... actually, is it currently set to 5 or 3? if it is currently 3 that would explain why slim doesn't start.
    2) at a tty in runlevel 3 use "xinit" instead of "startx".  Startx is fine most of the time, but it is essentially just a complex wrapper for xinit.  That complexity can often iadd useful functionality, but it *always* makes troubleshooting more difficult.  So for now just use a vanilla 'xinit'.
    3) remove dbus-launch from your exec line in xinitrc.  This is done by console-kit so it is redundant and potentially problematic.  Further BOTH of these are taken care of by slim, so I'd even suggest getting both a jump start on being ready for slim and simplifying troubleshooting by removing both of them.  Just make that line "exec openbox-session"
    Edit: adding one more:
    4) temporarily switch out openbox-session for openbox.  I suspect the reason feh's setting of the background is getting overridden is due to a script or setting in openbox's autostart settings - many of these are only invoked when "openbox-session" is called, while "openbox" starts *just* the window manager itself.

  • Lens Correction not happening in RAW with PSE 10

    My Camera is in the list a FinePix HS10, I have done all the updates that are available.
    I tried doing searches but nothing came up that I could find a solution to this.
    When I shoot a raw+jpg of an item with straight lines (edges of a painting) the JPG version has the lens distortion corrected, however the raw does not and shows curves where there should be straight lines.  When I go to Camera Calibration screen it shows Process 2010 (current) and Camera profile shows Adobe Standard.  There are no additional Camera Profiles listed.
    I am at a loss as to what to do to resolve this and have the RAW compensate for the lens distortion and end up like the JPG file.  Is my camera supposed to show up in Camera Profiles?  This would be horrible if not being able to be corrected so I must be doing something wrong or missed a step.

    Elements using the Camera Raw plug-in doesn’t allow for lens-corrections.  Since you’ve posted your question in the Elements forum, is that what you’re using?  The much more expensive regular Photoshop hosting the camera-raw plug-in and the less-expensive Lightroom do allow selecting lens profile corrections.

  • Where can I find lens correction profiles for EF 17-35 f/2.8L lens using ACR 6.2?

    Using Photoshop CS5 Extended on iMac 10.6.4.
    I'm  working with wedding photos shot by a friend but I cannot find lens  correction profiles for Canon EOS 20D or the EF 17-35 f/2.8L lens. When I  search online it simply says "No online profiles found". Is there a  download for older lens profiles? I checked & I'm using ACR 6.2. I don't have the camera so there's no  way to take test photos to create my own profile. But, shouldn't there  be a profile available; the camera isn't that old?

    Go to DXO Pro and download the 30 day trial. It works very well for lens/body correction, and unlike Adobe, DXO maintains data on the older cameras and lenses. Updates will always have those available. Adobe is a latecomer to this part of the correction process, so as Ian said, no call, no supplier? Out of luck.
    http://www.dxo.com/intl/photo
    It's fair to note that DXO does not necessarily have a complete line of everything, like my Tamron 28 to 75 isn't available as a module. They do pay attention to demands, or lack therof,  that are not mainstream as well. But their offerings are excellent, and the tests, professional.

  • Lens correction for Tamron 17-50 2.8 could be better?

    This is WITHOUT lens profile correction.
    ... and this is WITH lens profile correction. Not very obvious, isn't it?
    Top right corner of a picture taken with the Tamron 17-50 2.8 at 17mm 5.6.
    The cup is NOT a funny but a straight one!!!

    Most probably, the slanting of the cup in the corner of the image is not created by distortion of the lens but by pointing the camera down.
    When the camera is not held level but pointed up or down, the sensor is not parallel with the vertical lines of the cup. This is the "Scheimpflug" phenomenon - google for this word and you'll get lots of results. The "Scheimpflug" phenomenon gets stronger towards the edges of the image.
    This is why architectural photographers use "view cameras" where you can adjust the angle of the film plane or the digital sensor plane so that it is parallel to the vertical lines of a building.
    You can adjust the slanting of the cup with the manual vertical slider in Lens Correction,  and you might have to adjust the horizontal slider as well. The trade off is that that now your image will be severely "keystoned" and that is probably not what you want.
    But you cannot blame the lens profile. The lens profile corrects only distortion by the lens., not distortion by the "Scheimpflug" principle.
    PS: A tilt-shift lens will also correct distortions of the "Scheimpflug" principle.

  • Missing Guide lines

    I am using DVD Studio Pro 3.
    Can't make the guide lines show up for lining up the text in the menu.
    In the Alignment preferences I have checked, rulers=show, Units=show, Guides= show, and Show Dynamic Guides at object center, Show Dynamic Guides at object edges. What am I missing? Can't find any preferences to toss to start over at default.

    Hi Hal,
    I sure thought your suggestion would do the trick, but alas, no guide lines. I guess I was looking at the correct preference file in the 2 Libraries, just didn't recognize the name formation. I can change the ruler option in the program's preference file, but no guide lines. I can live without them, but just can't figure out where and when they disappeared. Would reinstalling DVDSP work? Hate to mess up anything else. I really like this program, suits me very well.

  • Tutorials on ACR 6.1 new Lens Correction features

    Hi,
    We are all experienced users of cameras/Photoshop/ACR etc., and wizards at learning by trial-and-error, but I think it might be really helpful if there was a good tutorial (preferably by Adobe), to deal with the new features of lens corrections in ACR 6.1, to take out some of the guesswork.
    There are items to be addressed, like for instance, the difference between Default-Auto-Custom in Lens Profiles page, why the lens profiles seem to depend only on lens type, while in Photoshop they depend on Camera/Lens combinations, how to prevent double correction, and many others.
    If anyone knows of such tutorials, I'll be grateful if they can share.
    Thanks,
    Moshe

    The "Chicken Little" as you call it, isn't aimed at you, unless you want to claim ownership. It isn't mine either. The sky's not falling but there are a few heavy showers about.
    I have taken the time and if you examine what I said, I am including the auto corrections in PhotoMerge as part of the whole. Particularly Photomerge at this point.
    If you have taken the time to read what I said I pointed out that Lens Correction will attempt to correct the image if you ignore the warning that no profile exists. I couldn't know that unless I tested it.
    If you took the time to read my posts earlier in the Profile Creator Forum, would would know that I actually ran tests on the Lens Profiler for the one lens in Adobe's collection I use, against the DXO output and found Adobe's correction way out of line. And to put to rest the notion I don't know what I am talking about, I have used this lens with architectural subjects and the barrel/pincushion distortion is very well corrected with DXO.
    But then you are busy I'm sure and would not necessarily know or remember all that. Strange, you do recall just enough to give you ammunition to insult.
    So bottom line for me is this:
    Lens Correct is set unchecked. I'll look from time to time as more corrections show up, and if I find them satisfactory and at least equivalent to DXO, I'll use it. Why not? It fits the workflow so much better. And I'll come back and share my findings. So Lens Correction in ACR won't affect me.
    Photomerge using Geometric Correction in Auto is a non-starter. I really like it better for some stitches than Reposition, but Reposition in CS3 is better than Reposition in CS5 (or 4) which is why I would go back to it.
    Yes, it is complicated, complex even. What I am doing is simplifying it best I can so I can work at photography, not test and measurement.
